The Incidence and Effects of Needle Sick Injury
Estimated Number of Needle Stick Injuries per Year in the National Health Service in the UK.
100,000(Royal College of Nurses , www.needlestickforum.net)
Studies Report that up to 56% of Dentistssuffer at least one Needle-stick Injury per Year.
(Felix DH et al. 1994, www.ncbi.nlm.nih.gov, Br Dent J. 1994 Mar 5;176(5):180-4.)
One Third of all reported Sharps Injuries in Dental Practice
are due to the Use of Non-disposable Syringes, Most Injuries occur during the Removal and
Disposal of Needles.
(Zakrzewska JM et al. 2001, Br Dent J. 2001 Jan 27;190: 88-92.)
The Vast Majority of Injuries occur after the Injection has been administered(Safer Needles Network 2006, www.needlestickforum.net)

The Incidence and Effects of Needle Sick Injury
Risks Factors
Dentists often reuse the Syringe on the Same Patient to administer Additional Doses of Anaesthetic.
The Syringe is passed between Dentist and Nurse (often repeatedly).
The Syringe Body is not disposable and requires dismantling at the End of the Visit.
Risk of Legal Action by a Dental Assistantif Best Practice not followed
Dental Assistants suffer Higher Rate of Injury
Increasing Regulatory Pressures.
There is currently no System on the Market that feels like the Traditional Syringe that Dentists are accustomed to which offers Complete and Full Protection from start to finish of the Whole Process.
Risks Factors
1. To Use existing Screw-on Needles
2. To Use existing Anaesthetic Cartridges (1.8 & 2.2 ml)
2. To have Aspirating or Non-aspirating Facility
3. To enable the Cartridge End of Needle to be seen
if Blood is Aspirated
